Acts 15:37-40

³⁷Barnabas wanted to take John, called Mark, along with them also. ³⁸But Paul kept insisting that they should not take him along who had deserted them in Pamphylia and had not gone with them to the work. ³⁹And there occurred such a sharp disagreement that they separated from one another, and Barnabas took Mark with him and sailed away to Cyprus. ⁴⁰But Paul chose Silas and left, being committed by the brethren to the grace of the Lord.
